EEPORT ON THE BOTANY OF THE ATLANTIC ISLANDS. 73 



in Mr Latham's garden ; introduced from Bermuda, where it is said to be indigenous, and 

 called the Great Palmetto." 



The confusion regarding this palm is almost endless. Martius states that Jacquin the 

 elder first introduced it into European gardens, whereas Jacquin himself says that the only 

 plant possessed by the Schcenbrnnn garden was obtained from Holland. Moreover, he was 

 under the impression that it was the true Corypha umbraculifera, and gives Malabar as 

 the native country. Martius quotes Hayti and Cuba as the home of the Sabal umbracu- 

 lifera, where he says it was frequent, and the leaves were used by the natives for roofing ; 

 yet we have seen no specimens of it from either of those islands. The figures and descrip- 

 tion in Martius's book seem to have been made from the Bermuda palm. 



The present dimensions of the large specimen in the palm-house at Kew are : — Height 

 of naked trunk, twenty feet ; height of head from the base of the lower leaves to the tips 

 of the uppermost, twenty feet ; spread of leaves, twenty-five feet ; circumference of trunk 

 one foot from the ground, four feet.
